FRICTION AL AIR-COIISIPRES SOR.

Specification of Letters latent.

Application filed August 7'; 1309. Serial No. 511,792.

' To allwhom it may concern:

- lowing is a full, clear, and exact description thereof, reference being had to theaccompanying drawings, which form part'ofthis specification.

- -This invention is an improved air pump or compressor, particularly designed for use on automobiles, and adapted to besecured adjacent to the fiv-wheel of the motor thereof, so that it can be driven by frictional con tact therewith when desired and. furnish com pressed air for inflating the pneumatic tires of such vehicle.

-The invention consists in the novel constructionand arrangement of parts wherein the driving crank wheel of the pump is mounted on a pivotal support so that it can be swung. relatively to the cylinder-into or out of contact with the fiy-wheel of the engine, and the cylinder is adjustably mounted so that it can be set at any desired angle to the fiy-whcel. and whereby on the conipression stroke of the pump the piston will be operated in the most advantageous manner.

I will describe the invention with refer' ence to -the accompanying drawings in which I Figure 1 alside'elevation of the apparatusin position for use. Fig. 2 is an en larged side view thereof. Fig. 3 is a. front view of Fig. 2, partly in section.

The pump comprises a cylinder 1 which may be ribbed for strengtheningand'L air cooling same, and which is open atone end and closed at the other end, by which end it supported on a bracket 9 attached. to the running gear of anautornobile (not shown) said cylinder being adjustably secured to the bracket 9 by means of bolts'l 1, passed through said support and tapped into recesses in the closed end of the cylinder. Said bolts 1*, 1, are so arranged, that by loos'i'xr.-

ing one bolt andtighteningthe other the cylinder 1 (which may have a bearing on the bracket intermediate the bolts as indicated in Fig. 2) can be tilted relatively to the support 9 and secured in any positionto which itis adjusted, This enables the cylinder to be adjusted angularly relatively to the flywheel W of the motor (not shown).

Within the cylinder 1 is a piston 2 con nected to a pitman rod 2 which is int urn connected to a crank pin 3 on a fly wheel 3' journaled' on astud P attached to a. swing able lever 4, which is .pivoted at its lower end'on a bolt 1-attached to the cylinder as shown. This enables the crank-wheel 3 and Patented Nov. 15, 910. 7

consequently itman 2 (which'is pivotally I connectedtot e piston as indicated at 2*) to he vibrated orswung so as to move the pcriphery of crank wheel 3 into contactwith the motorfiy wheel W as indicatedin dotted lines Fig. 2,so that motion will be imparted to the pistonfrom wheel 3 when the latter is actuated by frictional contact with fly wheel W. Preferably the. wheel 3 has a fach1g3 of leatheror other suitable frictional material. Lever Loan be swung so as to move crank wheel 3 to and from wheel W, by suitable means. As shown a cam 5is pivotally mounted besidethe lever 4: on a pin 1 attached to the cylinder 1'. This cam 5 engages a finger 4 on the side of lever t, and the cam is so formed that when it is rocked in one direction the lever 4 is moved so as to bring wheel 3 forcibly into contact with wheel W, whereupon the piston will be reciprocated, and when the cam is thrown in the opposite direction the lever t is moved so as to scparatewheel 3 fromwhcellV whereupon the pump is stopped.

The cylinder 1 has a port 1 in its lower end to which is connected a pipe G provided .a pipe '7 which. may be. led to any suitable point on the machine from which'it can be conveniently connected by rubber tubing to the tire to be inflated. At a suitable point a relief valve 7 may be placed in pipe 7 so tubes has'been obtained this valve will pop and notis'y theoperator, and also prevent excessive pressure in the tire. The cylinder is so adjusted, when secured toan automot'hatwhen the desired pressure inthe tire bile, that when lever L is moved to'bring the crank wheel 3 into cont-act with wheel'VV the pitman 2 on the down or working stroke of the piston will be practically in line with the axis of the-cylinder at the time of the greatest conpi'ession, thus'obtaining the effect of an 0 rest crank which ives increased power. The pipe 7 might be dicated-in Fig. 1 beyond the pop valve 7 and extended to the front and rear of the automobile in convenient position for attachranched as in merit of the rubber tubing in a Well understood manner.

The cam 5 may be operated by hand, or it may be operated from any convenient point on the machinebby means of a rod 8 com x the fly Wheel and the crank Wheel is n1ounted 'ona pivoted support which can be moved to shift the fly Wheel without disturbing the cylinder, and the air pipes are not in motion While the compressor is'running.

The invention While particularly designed for automoblles, 1s also useful in many cases Where it may be desired to compress air 111- termittently from the engine or fly Wheel of an engine or other motor. The pump could also be located adjacent any driven Wheel and operated thereby, as it is operated from the fly Wheel W.

Having described my invention What I claim as vnew and desire'tosecure byLetters Patent thereon is 1. In an air compressing apparatus for automobiles and the like, the combination with the fly wheel of the motor, ofan air' pump beside the fly Wheel comprising a Wafers? cylinder adjacent the r'nctor fiyflvheel, a preton therein, a lever pivoted beside on the cylinder, a'crank Wheeljourna-led in the free end of said lever, a pitman pivotally connected to the piston and said crank'wheel, a cam pivoted in the cylinder for shifting the lever, and a pipe for conducting air from the pump to the tire.

2. An air compressor for automobiles and the like comprising a cylinder adapted to be supported adjacent the fly Wheel of a motor, a support for said cylinder, bolts securing said cylinder to said support and whereby it can be adjusted angularly relatively to the perlphery of the fly Wheel, a lever pivoted'to and beside sald cylinder, a crank yvhoel' mounted on'the free end of said lever and movable thereby into or out of contact with i the fly wheel of the motor, a piston iirsaid cylinder, a pitman plvotally connected to said piston and to said crank Wheel, a valved air pipe connected with the closed end of said cylinder, a cam pivoted on the cylinder and engaging said lever, and means for operating said into or out of engagement with the fly whee of the motor.

cam so as to move the crank Wheel Y In'testimony that I clain' the foregoing as my own, I aflix lily-signature in presence of two Witnesses. Y
